To all whom it mary concern:

Be it known. that I, WILLIAM H. SMYTH, a citizen of the United States, residing at Berkeley, Alameda county, State of California, have l invented an Improvement -in Machines for Making the Bodiesvof Cans and other Packing-Vessels; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of machines for folding and fastening sheets ofvma'- terial into bodies, for use as cans, and other vessels for packing purposes.

My invention consists in the novel construction, arrangement, and combination lof the several parts which I shall hereinafter fully describe, and specifically claim.

The object of my invention is to provide a machine for this purpose which shall be effective and rapid in its operation, whereby its capacity and general usefulness are materially increased, resnltingin amarked economy in the manufacture of such bodies.

Referring to the accompanying drawings,- Figure l isa longitudinal vertical section on the line az-w of Fig. 3., Fig. 2 is atransverse,

vertical s'ectionon the line y-y of Fig. 3.

Fig. 3 is a. plan. Fig. 4 is a side elevation Fig. 5 (Sheet l) is a detail of the upper section c of the folder C. Fig. 6 is a cross section of the mandrel showing the insulated soldering strip.

A is the framel having atv its top the par, allel side slides a, upon which is mounted a, carriage B. This carriage as seen in Fig.

is of an open character having connected cross ends. To these ends are connected the folders represented by-C and C. These fold-` ers are made in sections, whereby they are enabled to be extended vertically to an open position as shown by C in Fig. 1, and turned into a folded or annular form as shown by C The folders may each be formed of any suitable number of sections,`though the preferable'for'm and number are those here shown and consisting of a fixed centrall section o secured to the carriage ends, an upper section c hinged to the top of the central section, a lower section c2 hinged to the bottom of the central section, and an end section c3 hinged to the lower end of the lower y section. These folders have a length equal to the width of the open center of the carriage .B as shown in Fig. 2. In each end ofthe carriage B is formed an approximately vertical chute orV channel b, (Fig. l) which is adapted to receive a sheet of material, represented by b', from which the body of the can or othergvessel is to be formed, and also with a chute or channel b2 to receive a sheetl of solder represented by b3, the lower ends of both chutes beingjust in front of the vertical plane of the extended or openfolder, as shown in Fig. l.

Dfis a cross-head l(Figs.l2 and 3). It is a rigid arch spanning the main frame and supported upon it by blocks d d which slide upon the top of the main frame. blocks are secured the engine cylinders E and E', one on each side, and having pistons e e', the rods e2 of which are connected with the aligned mandrels G G', which are seated in the 1 blocks dd', and are adapted to be Withdrawn into and to be projectedl from them. The mandrels move crosswise of the machine, and meet in the middle as shown in Fig. 2. The location of the cross-head D is in a verticalI plane intermediate of the ends 'of carriage B, and the mandrels lie in the horizontal `plane of the central or fixed section of folders O C as shown in Figs. l and 2.

It will be seen from the foregoing description that, assuming a sheet of material to be fed down in front of the open folder C in I Fig. 1,v and between it and the projected mandrel, and tangential thereto, the movement of cross-headD to the right will carry said man` drel into contact with the sheet, and press and hold it against the vfixed central section c of the folder. Continued movement of the cross-head and yof the mand-rel it carries, will, thereupon, by contact, move the carriage B alongwith it to the right; and it is during and and by reason of this movement that the closing of the folder, to form the sheet of material around the mandrel is effected. The means for operating the folders are as follows: Referring to Fig. l, it will, be seen that tothe back of the upper section c Vof the folder is secured a crank arm c4,l to which is connected an adjustable link c5, the end of which is fitted with a roller stud c6, which travels in ya cam To these IOO groove a. of the main frame. This groove is horizontal throughout the greater portion yof its length, but at its inner end it inclines downwardly, as shown in Fig. l,tl1e effect being, when the roller stud cG is in the inclined portion, as shown in the right hand folder O', to raise the upper section c to a vertical plane, and when in the horizontal portion to throw said section over into its place in the circle of the closed'folder, as shown in the folder on the left.

To the back of the lower section c2 is fitted a roller stud cw, which is adapted to travel under a horizontal track a2 on the main frame. This track bears at its inner end against the back of section c2, and when the folder moves outwardly, this contact serves to start said section upwardly on its folding movement, and thereafter the roller stud cw holds it. To the back of the end section c3 is secured a lever arm c8 to which is connected an adjustable link c, having in its outer end a roller stud c7 which travels upon acurved cam track a3, the upper end of which joins the slides a of the main frame. The eect of the curved cam track d3 is to lower the end section c3 as shown on the right, and to raise it again, and the effect of the horizontal slide a is to hold said section to its curve in the closed folder, as shown on the left. The adjustable links c5 and o9 permit the accurate adjustment of the interior diameter of each folder to suit the dierent sizes of cans and to insure their equal diameters. The mandrels G and G are retractible through the timely movements of the pistons e and e', the cylinders being supplied with the expansible or power medium through the flexible connections t from a pump I, shown in Fig. 2, as connected with. and operated from the main power shaft J.

H is the discharge way at'the central portion of the frame A, Fig. 1, and adapted to receive the bodies from the middle of the machine.

The operation of the parts thus far described may be set forth at this point with advantage. Referring to Fig. l, let it be assumed that a sheet of material be fed and held just in front of the holder C', and that the cross-head and projected mandrels are moving to the right. Byy contact with the sheet and pressure of the mandrels against the folder, the carriage B is moved to the right. At once the upper section c of the folder closes inwardly against the top of the sheet, and the lower section c2 and end section c3 also close in against the lower portion of the sheet, these movements being due tothe movement of the carriage, and t-hus they fold said sheet around the mandrels and hold it there. Now when the parts have arrived nearly at the end of the stroke to the right, the mandrels are retracted from within the formed body, leaving the latter in the still closed folder, and the actuatir g devices of the folder sections at the left hand side of the carriage have come to the inner portions of their cam tracks and grooves, whereby they are opened out and lie vertically extended, and this completes the stroke. Now the cross-head returns, and with its mandrels still withdrawn, it leaves the carriage which now remains at rest, and moves toward and just past the center of the machine. Before it; reaches this point, how ever, its mandrels are once more projected, and thereupon, coming in contact with the sheet of material fed to the left-hand folder, the carriage is moved over to the left, the sectional folder closing in about the sheet and forming it about the mandrels. During this movement to the left, the closed folder on the right, with its contained body or tube is brought to the central portion of the machine, and there the sections of the folder opening, drop the body or tube out into the discharge Way l-I, and assume the position shown in Fig. l, ready to receive another sheet of material. Then upon the return of the cross-head and mandrels, the operation is repeated, and the carriage, moving to the right, brings and discharges centrally the body or tube formed on the left. The valve motion for distributing the steam, air, water, or other uid properly to the cylinders E and E, in order to operate their pistons and to project and retract the mandrels is shown in Figs. 2, 3, and 4, and particularly in Fig. 3.

T is asuitable distributing valve, connected properly with the cylinders. The stemt of the valve has a lever t', to the free end of which is connected a rod t2, the other end of the rod being provided with two points of connection, t3 and t4, at right angles to each other.

IOO

Upon the upper surface of the sliding blocksI d and d of the cross-head D, are secured vertical pins t5 and t, upon which are j ournaled tappets t7, t8, t9, and t1, each set at a different level, and connected in pairs, the tappets t7 and t8 being connected and adapted to operate in unison, and t9 and tu being similarly connected. Upon the pins t6 and t5 are also journaled the levers t and #2 respectively, the former being connected with rod t2 at the connection t3, and the latter at the connection t4, and said tappets are also connected rigidly respectively with tappets t9, 1510, and tappets 257,155. Upon the sides of carriage B are the several fixed tappet pins V located in planes to receive the several contacts of the tappets,

whereby the valves T are operated at proper times. When 'the edges of the sheet are overlapped by the folder sections, they must be fastened in some way. In the case of metallic sheets, I provide for soldering them.

F is a soldering iron extending across the length of the cross-head frame D, in which it is carried. This iron is attached to aweightblock F', the ends of which have rollers f2 (Fig. 2) which are adapted to roll upon the elevated tracks a4 of the main frame, and thus to carry and support the block and soldering iron. The tracks a4 are not continuous, but as shown in Fig. 1, are separated by depressions a which provide for the removal of supportfrom under the rollers f2, to permit 4the soldering iron to drop down to its` IIO work. The weight-block and soldering iron are mounted in the cross-head frame D in such a manner that they may have free vertical movement, in which they are guided and.v

maintained by flat guide pieces f4 (Fig. 2). The weight-block F also serves as a hood for the soldering iron, directing and confining the flames supplied thereto, 'and forming a combustion chamber. Burners ff attached to the cross-head D (Fig. 2).are adapted to project flames down through openings in the weight-block into the channel ot' the soldering iron, and within the combustion chamber formed by said block serving as a hood. Now, regarding simply the vertical movement of the soldering iron,its time in the operation is as follows: When, in the outward stroke of the cross-head and mandrels from the center, the latter have reached a point at which the folder has bent the sheet of material around the man drels, then the rollers f2 ofthe weight-l block F leave ,the end of the middle'section of track a4, and lie over the depressions a5, whereby the soldering iron comes down upon the overlapped edges of the formed sheet. It remains in this contact until the mandrels have advanced sufficiently to enable the iron to complete its work, whereupon its rollers f2 reaching the outer section of track a4, the soldering iron is raised from the body or tube,

4 and the solder is thus given time to cool.

A reciprocating transverse movement is given to the soldering iron in order to iron out and complete the soldering of the joint of the body or tube, by means of the following devices:

S is a horizontal shaft (Fig. l) running parallel to the length of the machine and mounted thereon in suitable bearings s, and having at one end a pulley s connected with a pnlleyj on the main shaft J below, whereby shaft S is rotated. The shaft S is formed with a longitudinal feather way s2 (Fig. 4) and upon the shaft is an eccentric s3 (Fig. 2) fitted by a key s4 to the feather way s2 of the shaft, whereby the eccentric can slide longitudinally on the shaft, but will still be turned thereby. The eccentric operates between the yoke-shaped pieces f4 on the ends of the weight-block F', and thus imparts to said block and the soldering iron the necessary transverse movement. v

To supply the solder, I have herein shown the following devices: The soldcrsheet b3 in channel b? rests with its lower edge upon the top plate c of the upper section c of the folder and immediately in front of the sharp ened edge of a plate c12 secured to said folder section, (Figs. 5 and l.) N ow, when the folder section closes, the sharp edge of plate ci? will cut off a strip of solder which will be deposited upon the joint ready for the soldering iron. Referring to Fig. 5, it will be seen that the top plate c11 of the upper folder section c has its lip projecting from the section and intersecting the line of curvature thereof. The object of this is to insure the pressing ldown and in of the edge of the sheet upon the mandrel. This top plate is adjustable forward and back to regulate the position of its pressing lip, its adjustability being effected by means of an elongated slot csin said plate fitting over a screw C14 and a set screw C15 operating from the back.

The means for feeding the sheets of material vto position between the open 'folders andthe `to receiv'ejand to support the sheets when drawn down, and to relieve them of the nip pers. When the rack bar O moves upwardly, the fixed jaw of the nippers comes in contact with the hinged support B and forces it backwardly, thereby allowing the sheet b to drop into the nippers, the movable jaw being opened by contact with the front edge of the channel b. Then, when the nippers move down, they carry the sheet with them, until the lower edge of the sheet comes upon the l fixed stops Q and being arrested the sheet will be withdrawn from the nippers which continue their descent.

The several power transmitting connections are as fo1lows:-J is the main driving shaft with fast and loose pulleysjj. This shaft (Fig. l) has a worm'j which engages aworm gear K on the counter shaft K, which is provided with crank wheels k lo (Figs. 2 and 3). To these are connected `rods L, the outer ends of which are connected to rock arms M, the yupper ends ot' said rock arms being connected by rods N (Fig. l) with the cross-head `frame D. Thus the cross-head is reciprocated. Engaging with the rack bar 0,'of the feed nippers, is a pinion P on a horizontal shaftp mounted in the main frame. Upon the outer end of shaft p is another pinion P which engages with a segmental rack P2, the shank of which is journaled at p in the main frame. The shank carries a roller stud p2 which is operated upon by a cam R upon the crank wheel k. Upon the pivotal shaft atp" of the segmental rack P2 is also secured a flat spring p3, which toward the upper extremity of its motion comes in contact with the lower portion of the'discharge way H, whereby the rack bar O is rendered quick and immediate. Thus the nippers are moved up and down to feed the sheets of material. In connection with the cross-head frame D, is a shaft F2 having a crank handle F3, and providedwith lifting arms F4 which play up under the yoke pieces f4 of the weight-block of the soldering iron whereby said iron may be raised up com- IIO I 25 beginning of the downward movement of the pletely out of the way when not in use. In order to prevent the rapid radiation of heat from the joint undergoing the soldering process, I have, as shown in Fig. 6, seated in a groove in the mandrels, a metallic strip 016 upon which the joint lies and receives the pressure of the soldering iron, and below this strip l have placed a strip c17 of some nonconducting material such as wood, so that the receiving strip is separated from the metallic body of the mandrel.

The full operation of the machine is as follows:-The sheet ZJ being placed in the receptacle b is supported by the hinged suport B', till in the course of the revolution of the crank wheel lc, the attached cam Rengages with the roller p2, thereby depressing the rear end of the shankof the segmental rack P2, and correspondingly raising the toothed end, which in its turn through its engagement with the pinion P rotates the shaft p and the pinion l?. This pinion being engaged with the rack bar O, the latter is thereby elevated, so bringing the stationary side of the feed nippers o2 in contact with the hinged support B', forcing it from under the sheet, and permitting the sheet to drop into the nippers. At the same time the loose side of the nipper comes in contact with the front edge of the receptacle h, thereby opening lit and permitting the sheet to fall between the jaws of the nippers. The continued motion of the cam R having raised the segmental rack P2 to its highestpoint., the further motion of the cam ermits of its downward course by the weight of the feeding device, assisted bythe pressure of the spring p3 against the lower side of the runway H, carrying down with it the sheet until it reaches the rest or stop Q, which prevents its further motion, and withdraws it from the nippers. It now rests loosely upon the stops Q andin front of the open folder. By this time the mandrels G and G have been projected toward each other, till they have met in the center of the machine, forming acontinual cylindrical bar, across the machine and in front of the sheet, which is tangential thereto and is between the mandrels and the open folder. The cross-head during this time that the feeding device has been operating to carry the sheet down, has been advancing from the end of the machine, at which is located the closed folder. The continued advance of the mandrels causes the latter to grasp the sheet between itself and the stationary portion of the open folder, carrying the sheet along with it; at the same time causing the folder to wrap around said mandrels whereby through the action of the several rollers connectedto the sections of the folder and their engagements with the various cam tracks and grooves, the sheet is now, by the sufficient advancement of the mandrels, wrapped around them; but during this operation, the upper section of the folder carrying the sharp plate 012 has severed from the sheet of solder b3 a thin sliver the whole length of the sheet, and

by the closing of the upper section c has deposited this sliver upon the joint of the folded body or tube. These combined actions of folding the sheet, cutting the solder and depositing it upon the joint have been accomplished while the mandrels have moved a certain distance, during which the soldering iron F has now arrived at that portion of the frame where the tracks which support it cease. The soldering iron immediately descends upon the `joint, melting the solder and forming the joint. The iron remains upon the joint until the cross-head and carriage have arrived at nearly the extremity of their journey, when the rollers f2 come to the track once more and are thereby elevated, raising the soldering iron from olf the joint. In order to facilitate the soldering and sweating, besides the motion already described in the soldering iron, it has a continuous horizontal reciprocation. The mandrels and the accompanying carriage continue some little distance beyond the point to which the soldering iron has been raised, to permit the molten solder to set, and then by the engagement of one of the tappets with the tappet stop, the valve T is operated and the mandrels withdrawn. The crosshead and mandrels continue their journey in the reverse direction, leaving the carriage stationary with its completed tube. Vhen it arrives near the center of the machine, the tappets again engage with another tappet stop which causes the mandrels to be again forced out to the center of the machine; the other nippers in the meanwhile having raised and secured another sheet, and the operation above described is repeated on the other end of the machine. During the accomplishment of this second operation, the carriage with its formed tube is moved backward to its former position, carrying with it its complete tube, which by the opening of its inclosing sectional folder deposits it in the discharge way H. In this it is temporarily held by the nippers, but as these rise it is permitted to roll down the inclined way H and be thereby discharged.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
